18;Claims. (Cl.164-84.5)

This invention relates to tape-dispensing-machines, and more particularly to 'a machine adapted for dispensing'pressure sensitive, so# called scotch, tape, or tape which is clingable or tacky uponone of more surfaces without the addition of a liquid.

The dispensing of scotch tape has presented certain problems in that one surface of the tape is tacky and will tend to cling to any lobject with which it comes in contact, and,`as the tape is usually Wound upon a roll with thetacky surface of one layer in engagement with thenontacky surface 'of the under layer', it requires an appreciable effort to draw the tape from the roll. Due to the fact that the tape tends to cling to any object with which it comes in contact, it is usually necessary, if the tape is drawn from the roll by some mechanical feeding means, to provide a stripper of some kind to strip the tape from the feeding means. Where thev tape'is grasped by the fingers and drawn from the machine, this stripping means-should be so'arranged as to provide a free projecting end portion of tape which can readily be grasped'by the operator.

It is contemplated by the present invention'toy provide a tape-dispensing machine in which the tape is drawn from the roll or from the machine by the operator Who grasps the free 'end of the tape and exerts a pull thereon. In addition,- how-- ever, there isvprovided a feeding member 'or drum' to which the tape lclings and which is adapted when rotated to draw the tape from'the roll, the rotation of the feeding member 'or drum 'being effected by the pull of the loperator on the free' end of the tape. .As will be hereinafter explained, the mechanism is so arranged to reduce the effort` required to draw the tape from the supply roll.`

There is also provided 'in the mechanism disclosed a severing. member against` which the tape maybe torn off, to which severing member is imparted an advancing movement during the. feeding operation and a reverse or receding;

movement after the completion of .the'feeding operation so as to eimose a free endof the tape and render it accessible 'to be grasped by the operator. Means are provided to lock the severing member against movement during the sever-y ingoperation and, at the same ftime, to'v provide for a previous forward movement of vthefeeding member to any extentnecessary in .order that thedesired quantity of tape may .bewithdrawn from the roll and .severed. Y

It is also contemplated inthe `present-'inven`` tionnto provide astripper .member vwhich--Wlllcooperate with the feed member-or drum, so thatthe free end of the tape will be positively stripped from thel drum and,l at the end of a cycle ofoperations,v will extend'i'reely from thedrurnV where it is in an accessible position to be grasped bythe operator. r 2 'One object of thepre'sent inventionis to pro# vide anew andimproveddevice for'dispensing tape... .g l v. A further object of the invention isr to provide a new and improved device for dispensing tape having the feed drum mounted on a moving or oscillatable arm, and a severing vmember or tear-off blade also mounted on'this arm and mov-'= able with respect tothe arm. y v:

A vstill further object of the invention is. to providel a new and' improvedv tape dispensing machine of the characterdescribedwin which the severing -member or tear-off bladel Will be moved forwardly during 'the feeding operation, and will be locked in its Avforward positionin" orderthat the tape may be readily torn off against the blade. f y Y Still another object 'of the invention is 'to provide a tape-dispensingy machine of the character described having' the feed 'stripper mecha-L nism-mounted on the oscillatable arm, the stripper mechanism being "actuated bythe movement of the arm, so'th'at, at the end of the returny stroke of the latter, the'stripping meansl will be moved tof-strip the freefend of the tape from the feeding means. y I y To these and "other ends the invention' consists in the" novel features and combinations of parts to be hereinafter described and claimed; In the accompanying drawings: Fig. 1` is a' front'elevational view of a tape` dispensing machine embodying our invention; f Fig: 2 is a side elevational viewI thereof; Fig. 3 is an enlarged sideelevational view "of certain 'of the partsr of the mechanism with the supply vroll of 'tape-removed Vand with the Voscillating armY shown in a `forwardposition;v I

Fig. 4 is a view similar'to Fig. 2 with the oscillating arm shown in' its rearward position at the' end of the return stroke; and Fig. 5 isfa detail sectional View on line 5-'5 of Fig. 1;v f I To illustrate a preferred embodiment -'of oui" inventionywe have shown "in'v the accompanying drawings a tape-dispensing'l machine 'comprisingv aframe in the formi of 'a'plate I0, the plate being supported in upright'position from the base' I'I` which may restfupon or be secured to a suitable support. ...Secured to the'frame member I0 is a shaft I2, and upon this shaft is rotatably mounted a relatively large gear I3, which, as will be explained later, serves as a rack rather than as a gear. Rotatably mounted on the shaft I2, as shown more especially in Fig. 2, this gear is restricted from rotation in a counterclock-wise direction doy ,a pawl I4 pivoted `to the Vvframe member vIl! at 'i5 .and Voverweighted at its rear end or tail portion I6, this end of the pawl resting upon a pin I1.

Also rotatably mounted on the shaft .I2i,s. an arm I9, this arm serving as a carrier member for the feeding means 29, the .latter `being vin the form of a drum and consisting fof :spaceddisklike elements 2I which are serrated -on their peripheral edges, so that the tacky surface of the tape will cling thereto only to ,a certaindegree and be drawn from the supply roll, as hereinafter explained. The feed drum 29 `is secured to a shaft 22 which is rotatably mounted in the armi' I291an'd projects :thereiromat the sideopposite-the feed drum. `A pinion :23 is vmounted on the Aprojecting end of this shaft, the teeth of :Whichfare in mesh-withfthose ,of-the gear fl3. From lthe foregoing, .it will :be -apparent `that, when the arm I9 is rocked in a counterclockwise direction, as fshowniin Fig. .2, the pinion 23 -will be fdra-wn lover the periphery of the gear I3, and, as the latter is locked against movement in this directionbyfthe -pawl I4, :the pinion will berotate'd and effect tlfieirotation of the feed drum r2.0.

`Aspring -isfcoiled1aboutaspacing 4collar 2E on l:the :shaft 1:2, one v,end Iof this spring being secured at 21 to the Aann l|19 :andrthe .other end being secured'at to aplate 29 secured at '39 to `Athe frame member I,-this plate having lan offset portion f3I ,fso that it kstands in spaced relation -with .the frame member IIJ :and upon the side :ofethe .arm I9 opposite v'the frame member. Ehespring 25 `tends to `returnthe arm I9 -to its rearward position, :shown in FigxZ, after it has been moved from this position.

Also :rotatably mounted on the :shaft I2 is a holder 32 to suppor'tthe :supply 'roll of -tape l3?. As ishownrin Fig. i1, `the roll of tape lies Asubstantially'infthesame-vertical plane as the-feed ldrum 20, fso'that the free vend f3# of the vtape (-Fig. -2) mayfbe trained around-'thefeed drum and project therefrom, as show-nat35, so lthat itl-maryvreadily be .grasped by the fingers of the operator.

On the side of the arm I9 adjacent the frame member 'Iii --is pivoted Van arm 31 (Fig. 5) which carries la pawl 38 :in .engagement-with the teeth of 4the pinion 23, 4this pawlfbeing urged toward the pinion by the .spring rt9 -secured -a-t one -end to--the arm`31 and'at the otherend to the carrier I9. AErima-whenthearm I9 is moved in a counterclockwisedirection, as :shown-in Fig. 2, or a clockwise direction, :as lshown in Fig. 5, the pinion will be free to rotate on the :teeth of the Arack gear :I3, lthe .latter "being held -against rotation. When, however, the arm I9 is returned to its rearward position Iby the spring 125, the pinion 23 .will beheld .against rotation and will effect rotation of the gear I3 in -a clockwise direction, as shown in which rotation-will be permitted by the pawl I4. Thus, as the pinion 23 does notrotate-onfthe reverse or rearward movementof thearm I9, there is no rotation of the F feed drum wzl) .at this time.

,-In--order--that measured lengths of tape may be dispensed fromthe machine, a stop member Ml is .adjustably secured at the upper front portion Cif :the framefmember ,fI :by .a set screw 4I, -this ill) :periphery of the gear and be in position to be engaged `-by the pinion.

A severing member in the form of a tear-01T :blade-44 ris1mounte'd'upon the arm i9 adjacent thevperipl'reryof fthe feed drum, and a resilient stripping'blade'Mis-secured to the under surface of this memberwhich, by the inherent resilience of .the @stripping blade, will strip the tape from the blade if the tape tends to adhere thereto after a `'severingoperation. The blade I4 is carried by an arm 46 pivoted :to the member I9 at 41, so Athat theiblade may rrock -swith respect to fthe arm and with relation to rthe .axis of Athe zfee'd drum .2 Il. Afspring "49 .secured :fat one i. end tto the member ."I 9 `as :at .49 .and secured at .its yother end to therarmftendsfto:urge the flatter in a counterclockwise direction about the-pivot 41, as-shown in Figs, when the.armiIB is Ain;a forwardposition. =IIowever at the fend of .the return movementof the 'arm `I9,.or-wfhen fthe-latter is in its rearward position, fa .cam shoulder 50 'on the lower end Yof -the -arm 145 will strike a fcam vmember :5I on the `plate .-29 to :move -thearm 4,6 in fa clockwise'direction .about its pivot 41 .to 'the position shown 4int-Fig. l'2. It-will be :apparent that in this 4position the severing 1'member 4'4 is moved rearwardly vwith respect to ithe `axis "'22 of the feed drum lso fas to expose a larger portionof the-'tape engaged withfthis drum, Vand:particularly expose the free end 535,'so y.that 'it maybe grasped with ease. `When, however, the arm I9 is moved forwardly Vin :a feeding fmovement, the severing member IM lwill Yalso be moved forwardly to the position v.shown in rFig. 3, so that the tape -wil-l be.'severed at apoint'forwardly ofthe feed drum, thus leaving the free end 35 when the severing member `is returned to the position shown Iin Fig. 2.

in order that the -severing member 4t -will be held in position `during the severing roperation and not move rearwardlyagainst vthe-tension of the spring 48 by l'pressure of "the tape against the severi-ng edge-we have provided the llatch member 52, which is secured to a `hub 52e rotatably mounted uponithe shaft I2. This latch member is provided with -a ange 53 having lthereon a latch dog 54 adapted to engage over a pin 55 secured to -atailpiece 56 forming the lower end of the arm 46. It will vbe apparent that the flange 53 vextends across -the edge of the arm I 9, so that the latch member -Wiube moved forwardly with the -arm I9. The `rearward or clockwise movement ofthe `latch member is limited, however, by engagement of its edge with the .stop 51 on a' plate -58 4secured to the plate 2,9 but lying on the opposite side of the l,arm IS. Aspring secured at one end to the arm I9 at a point opposite the pin 21 and secured at the other .end as atl .to the-latch member 5,2 tends to urge the nange ,5t toward the arm I9. VAIt will be noted that inthe rearward position of the arm I9, `as shown in Fig. 2, the ange 5,3 will be held in a `position spaced. from vthe Aforward edge of thearm ,I9 by .the stop 51, and the pin on the arm ,5,6 Will llie ina position adjacent -the upper ,edge of .this flange. When the arm 'I9 is moved in a counterclockwise 57- direction `or in' the'direction to'feed tape, the cam surface U -will be moved awayffrom the 'surface- 5I, land the arm 46 will be moved ina counterclockwise direction about vits-'pivot 411 relatively tothe arm I9 until the pin 55 strikes againsta shoulder 63 on the forward edge of the arm I9 which will arrest the movement of the severing' member. f

This is the position shown in Fig. 4, and continued forward movement of the arm I9 moves the pin 55 below the latch dog' 54, so that the severing` member will be locked in this position with respect to the arm I 9; vFurther forward movement of the latter moves the latch member 52 with it, whichmovement will continue until th'e-y pinion 23 strikes thel stop member 42 which may be the position shown in Fig. 3 in wlrchthe latch member 52 is moved away from the member 51. It is understood that this latch member willbe carried along with the arm I9 throughout the continued movement of the latter regardless of 'where the stop 42 may be set.

The tape will be torn off by moving it upwardly against the severing member 44 at the end of the forward movement of the arm I9, presumably in ther position shown in Fig. f3. Thereafter, the arm I9 will be returned rearwardlyto its original position by the spring 25. Thev arm 46 carrying the severing member WillV remain locked in position, as shown in Fig. 3, until the latch member 5,2 strikes against the stop 51, as `shown in Figs.`

land 5. This will arrest the ymovement of the latch member, and the arm I9 will continue te move rearwardly without it. At about the time that the latch member strikes the stop 51, 'the cam surface 50 on the arm 46 will engage the oam surface 5I and will move thearm 46 in a clockwise direction (Fig. 4) about its ,pivot 41 to the' original position shown inFig. 2, thus moving the" severing member 44 with respect to the feed drum.I

to'expose the free end of the tape. The rearward or return movement of the arm I 9 is checked by a rounded portion 65 of the arm 416 coming in vcontact with an arcuate edge portion 66 of the arm 29. the stop'member to limit the reverse or return movement of the feedl mechanism.

f "When the dispensed portion of the tape is torn. eff against the severing member, a free end will.. be left which will normally `be out of contact Thus, the arm 4B servesas withthe feed member 2l). However, it maybe that, in some instances, this end of the tape will become engaged with the feedv drum and will not extendfreely therefrom, as shown in Fig. 2. In

order to insure .a free projectingend which ,may`

be readily graspedby the operator, we have provided a stripping means in `the `form of a plurality' ofjblades 68 which extend into the spacesbe.-

tweenthe disks 2l, these stripping blades being carried by a plate 69 reciprocably, mounted on. the arm I9. For this purpose, the plate G9 is provided with slots1l in which arel received headed members-1I secured to the-arm I9. lThe mernfber 69 is cutawayat its rear surface providingv shoulders 12 and `13, and the tailpiece 56 of the' arm 46 extends through this cut-out portion to.

engage these shoulders,.so that the position of the stripping blades 68 iscontrolled by the arm 4E which carries the severing means.` In the position shown in Figs,v 3 and 4, for example, whenl thel tailpiece is in .its lowermost position and the severing member 44 is in its forward position relatively to the arm I9, thel stripping blades 68 @lidi-399.' by gif-avi?? 9: $118.11. .lQwermQstrostiQrr in which the pins 1I are at the'upp'er ends lofthe v slots/10,'so that upper end'sof the stripper blades will lie below :the upper y.periphery of the feed drum, When, however, the arm I 9 is in its rearward position, as shown in Fig. 2, and the tail- .piece 56 has been moved to itsupward position by engagement o'f thecam 5I) withthe cam surface 5I, the upper edge of the tailpiece 5E will engage the upper shoulder 12 and move the stripper blades upwardly as permitted by the slots 1D, so

that the upper ends of these blades will lie above the periphery of the feed drum and will assure that the free end of the tape is stripped therefrom to extend in a projected position, as shown in Fig. 2.

It is believed that the operationof the machine will be apparent from the foregoing, but

may be briefly described. With the parts in thel position shown in Fig. 2 in which the' tape 34 has been trained about the feed drum 2U, the operator grasps the free end 35 of the tape and pulls upon it in a forward direction. This tends to move the feed arm I9 forwardly, which in turn" than'the length ofl tape dispensed. "This gives the operator an advantage in" power with the result that less effort is'required to strip the tape fromv the roll than would be required if it were done by a straight pull upon the end of the tape.

AWhen forward movement of the arm I9 is arrested by engagement of the pinion 23 with the stop' 42, the operator pulls the tape upwardly againstthe severing member 44 and severs the q tape, the arm 46 being locked in position by the' latch` dog 54. Atk the time 'of the severing of the tape, the severing member 44 stands in the forward position shown in Fig. 3. When the tape is severed, `the arm I9' is automatically returned D to its original position by the spring 25. When the latch member 52 strikes the stop 51, the-tailpiece 56 of the'arm 46is released from the latch dog 54, and the severing member 44 is moved rearwardly by the engagement of the cam surfaces 50 and vESL-thus .exposing theend of the tape on the feed drum. `At `the same time, the stripper member 68 is moved upwardly by the tailpiece 56 to insure that the -free end of the tape standsin a projecting position, as shown in Fig. 2.

It will be understood that the forward movement of the severing member is effected by the spring 48, and, in like manner, upon rearward movement of the arm I9 the latch member 52 is caused to' follow the arm by action of the spring 6I). This spring, however, allows the arm I9 toy move rearwardly independently of the latch member when theflatter engages the stop 51 to release the pin 55. v

While we have shown and described anpreferred embodiment of our invention, it will be understood that it is not to -be limited to all'V of theA details shown, but is capable of modification and variation within thespirit of the invention f ,v andjwithin the scope ofy the claims.-
